SPRAY-LAMP FOR LIGHTING, HEATING, AND SIGNALING PURPOSES.

SPECIFICATION forming part of Letters Patent No. 452,390, dated May 19, 1891.

Application filed February 25, 1890. Serial No. 341,651. (No model.) Patented in England March 15, 1889, No. 4,504.

T0 on whom it may concern:

Be it known that I, GEORGE ROSE, a subject of the Queen of Great Britain, and a resident of the city of Glasgow, Scotland, have invented certain new and useful Improvements in and Connected with Spray-Lamps for Lighting, Heating, and Signaling Purposes, (for which I have obtained Letters Patent in Great Britain, No. 4,504, dated March 15, 1889,) of which the following is a specification.

This invention relates to that class of spraylamps for lighting, heating, and signaling purposes wherein compressed air or steam is used to spray the oil; and it has for its object to simplify and improve the construction and arrangement of the parts of lamps of this class.

In order that my said invention may be properly understood, I have hereunto appended an explanatory sheet of drawings, whereon- 1 Figure 1 is a side view, partly in section, of the head of the lamp with a signaling arrangement attached. Fig. 2 is a sectional view of a lamp-burner and combustion-box. Figs. 3, 4, and 5 represent, in side elevation, plan, and transverse section, respectively, a four-way cock.

On the drawings wherever the letters of reference are repeated similar or like parts are indicated.

Referring to Fig. 2, as will be seen, my improved lamp has a hollow cup-shaped burner A, in which the air or steam nipple J for spraying the oil is centrally secured, and communicates with a hollow air or steam chamber A forming the base of the burner, into which the steam or air supply is led by the pipe E. The dividing-partition A maybe cast in one piece with the burner A or secured therein. The burner A is surmounted by a combustion-box, which consists of an outer casing or cylinder 0, in which is supported concentrically by hangers C or equivalent another preferably shorter cylinder. In the annular space formed between these two cylindersIinsert a coil-pipe E for superheating the air or steam to spray the oil, one end of which is connected to pipe 13 and communicates by the passage F (in the solid piece a) and pipe H in the stand-tube G of the lamp with the air or steam supply, while the other end communicates by the pipe E with the chamber A of the burner. In some cases, and especially when the lower end of the outer cylinder 0 of the combustion-box is made tapered, (as shown,) so as to be easily fitted on the burner, instead of fitting the steam or air superheating coil-pipe E in the annular space between the concentric cylinders O D, it may occupy the space between the lower end of the inner cylinder D and the top of the burner A. At the point where the superheating coil-pipe E E joins the burner a small drip tube or chamber L may be fitted for collecting any condensed water or dirt. This drip-chamber would by preference be provided with asmall draw-off cook or tap M at its lower end. In this form of burner the oil is forced under pressure from the oiltank of the lamp up the stand-tube G through the channel a in the solid piece a, and so by the pipe Y to the annular space a formed between the wall of the burner-cup and an inner rim 0t cast in the cup. From the annular space a the oil trickles through holes a, formed in the rim or wall a or otherwise into the cup, and so to the point of the burnernipple J.

For the purpose of keeping a light continually burning in the combustion-box during the periods when the oil and air or steam supply to the burner is cutoff when the lamp is used for signaling purposes, I, by preference, insert in the annular space a an asbestus or other wick a which will keep a light during the periods between the flashes and will, on the oil spray being again turned on, instantly relight it. As will be seen, the oilpipe Y is preferably bent over, as shown, and the oil trickles onto the wick a; or the pipe Y may communicate directly with the oil cup or well of 'the burner. A cylindrical piece of perforated metal or wire-gauze D is preferably screwed into or on the lower 7 end of the burner-nipple for preventing grit N, Figs. 3,1, and 5. This valve or cook l\',which may be fitted on top of the stand tube of the lamp or on top of the basement tank or reservoir, in which is contained the oil, or in other convenient situation consists, preferably, of a hollow barrel of cylindrical or other shape having four openings or ways formed in it, two on each side, the two N N on one side constituting, respectively, the steam or air inlet and outlet, and the two N N" on the other side constituting, respectively, the oil inlet or outlet. In the barrel of the cock is fitted a plug or key P capable of being easily turned by a handle or wheel, as usual, and which has bored in it, two elbow-shaped channels or ways, as shown, which, when the cook or valve is turned slightly round, opens communication between the oil inlet N and outlet N and the air or steam inlet N and outlet N simultaneously. Likewise, when the plug is turned back or reversed, the air or steam and the oil are both shut off synchronously.

For the nice adjustment of the oil and air or steam supply, I by preference fit 011 the valve or cock a dial-plate O, a finger or pointer P fitted to the key or plug P of the valve or cook indicating thereon the degree to which the valve has been opened or closed.

The ways or channels in the key or plug, instead of being elbow-shaped, as hereinbefore described, may be straight, and the valve or cock may be otherwise slightly altered to meet varying circumstances.

The oil and the air or steam from the fourway valve or cock maybe led by two separate tubes G II to the burner. These tubes may be for the sake of compactness either both inelosed in a third tube, which may constitute the stand-pipe supporting the burner and combustion-box, or they may be inclosed the one within the other, as shown at Figs. 1 and 2, the tube Gbeing for oil and the tube H for air or steam. The oil before passing to the burner to be sprayed would preferably have its supply regulated and controlled by a regulating apparatus, as shown at Fig. 1, consisting of a hollow box or casing Q, surmounted by a suitable lid or cover Q, which may, if desired, be provided with an air-valve at top. A draw-oil cock may be fitted at the bottom of the casing, if required.

Into the box or casing Q is led the oil-supply pipe R, which has at its end an outletvalve S, which is preferably constructed of a solid piece S, forming the valve'seat, and having a plug 5 screwed into it. Through the plug works the valve-spindle, which is surmounted by the valve S. A small spring S is also provided for counterbalancing the weight of the float T. Any other suitable arrangement of valve may, however, be used.

The outflow of the oil through the valve S is regulated and controlled by the cylindrical float T. A ball or equivalent float may, however, be used instead of a cylindrical one. The spindle of the valve Sis connected to the iloat, so that when the oil in the casing rises above a certain level the float rises, and in so rising shuts the valve and cuts off the supply. lVhen the oil-level falls, the float also sinks, and so opens the valve S The oil issuing from the regulating box or easing Q is made to pass, for the purpose of preventing as far as possible any grit or dirt passingalong with the oil to the burner, by preference through a small cone U, having a hole at its apex situated in the pipe U leading to the burner.

In the view Fig. 1 the valve or cock N is shown as fitted on the oil-supply pipe U. In the arrangement shown in this figure the oil from the source of supply passes from the pipe G through a T-piece, pipe R, and siphon It to the oil-regulator Q, from whence it passes through the cone U into the valve N, and thence to the burner by the pipe Z). The air or steam likewise passes from the source of supply up the pipe II (shown partly in dotted lines) through the channel 11 (shown dotted) in the solid piece (Z and pipe connection c to the valve N, from whence it passes by the pipe fto the burner. \Vhen, however, the four-way valve is not used, the pipe U communicates direct with the burner, and a tap or valve is provided on it for opening and cutting off the oilsupply.

\Vhen it is desired to turn off the oil and air or steam, or the oil only, so as to put out or lower the flame when signaling, I prefer in all cases where the controlling valve or cock is situated some distance above the ground, or in the case of a vessel above the deck, to affix a quadrant Z, as shown attached to the cock N at Fig. 1, or a bell-crank lover or an equivalent device to the handle, key, or spindle of the valve or cook, which can be actuated by a cord or a wire or chains, so as to turn the key of the cock round and so turn the oil or air or steam, as thecasc maybe, on or off at will. In some cases where a bellcrank lever or quadrant is used a spring Z may be so fitted to one end as to keep the valve opened or closed, while a cord Z wire, rod, or equivalent is attached to the other end, and on being pulled from below closes or opens the valve.

In many instances the arrangements which have been described for the steam or air supply may be used for the oil-supply, and, vice versa, the oil-supply arrangements be used for the steam or air.

My improved lamp may be used for heat ing as well as illuminating and signaling purposes, and when so used in connection with any furnace arrangement for heating boilers, smelting, and other purposes the flame would by preference be directed horizontally into the furnace or chamber to be heated.

In my application, Serial No. 327,5l-S, tiled October 19, 1889, for improvements in steamspray lamps I have shown and claimed the stand-pipe II, and its interior plug, &c., also shown, but not claimed in this case.
